Common Emitter Configuration has maximum impedance.
They are both used for similar functions, such as oscillators, amplifiers, and switches. The vacuum tube was invented first, and has therefore been around longer than the transistor.
because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current
To get all the voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.

The three basic transistor connection configuration modes are common emitter, common base, and common collector. In the common emitter configuration, the emitter terminal is common to both the input and output circuits, providing high voltage gain. The common base configuration has the base terminal common to both circuits, offering high frequency response but low voltage gain. Finally, the common collector configuration, also known as an emitter follower, provides current gain and high input impedance while maintaining unity voltage gain.

That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
the gate is insulated from the channel by either a reverse biased junction or silicon dioxide.
Bootstrapping is used to allow bias to be applied to the base of a transistor while maintaining a very high input impedance.
Base resistance (Rb) is the resistance seen by the base terminal of a transistor when analyzing its behavior in a circuit. It is a parameter used to model the input impedance of the transistor and is crucial in determining the biasing and signal amplification characteristics of the transistor circuit.
MOSFET has high input impedance in comparisson with JFET due to the insulation material of silicon dioxide
FET s have very high input impedance when compared with Bipolar transistors.
